To provide a vehicle weight change detection system and a vehicle weight change detection method for accurately detecting a weight change which is equivalent to the body weight of a passenger without individually installing the vehicle weight change detection system for each vehicle.
The vehicle weight change detection system for detecting a weight change which is equivalent to the body weight of a passenger includes: planar weight measurement means 1 for measuring the weight of a vehicle 50 in a state that at least one of wheels 51 of the vehicle 50 runs on the weight measurement means 1; weight detection means 2 for detecting the weight change of the vehicle 50 by measuring the output of the weight measurement means 1 in measurement timing at each predetermined interval, and for determining whether or not the amount of weight change is the amount of change which is equivalent to the body weight of a person; and warning means 3 for, when it is determined that the amount of weight change of the vehicle 50 is equal to or more than the amount of change which is equivalent to the weight of the person by the weight detection means 2, issuing a warning of the result.
